| Abstract Scope |
Epoxy composites reinforced with 10,20 and 30% v/v of a scientifically new natural lignocellulosic fiber in terms of its use as an engineering material known in Brazil as seven-islands-sedge were, for this reason, investigated for mechanical properties associated with Izod impac test. The specimens dimensions followed the ASTM D256 standard. The results have shown that composites of 30%v/v presents more effective reinforcement. The statitiscal analysis of the data of impact energy obtained, were performed by Weibull analysis, ANOVA statistics ad Tukey test. Both of the Anova and Tukey test analysis were based on a 95% confidence level, therefore, the Tukey test confirmed that the reinforcement of 30%v/v presents the highest absorption energy altough it just have shown a significant difference for a pure epoxy matrix and 10% of volume fraction reinforcing composites. The weibull analysis exhibited a satisfactory linear adjustment confirming an homogeneity in the specimens group. |
